PIPE CONNECTIONS REFRIGERANT CONNECTIONS Refrigerant connections on outdoor unit NOTE: The unit is supplied with welded connections. As an, service valves are available for liquid and gas lines with welded connection. As an, refrigerant factory precharged kit is available (this includes service valves). SEE OPTION SECTION IN THIS MANUAL (pg. 22) Piping connection lines For calculating piping connection lines between outdoor and indoor units, distance and drop between lines are very important aspects. To achieve the best features for the units, take special care about: - The gas line must be always insulated. - The horizontal lines must be sloped at least 2% toward the outdoor unit. - The minimum speed suction must not be below 6 m/s on the vertical line of the gas line, and siphons must be installed every few meters upward to assure the oil returns to the compressor properly. - The maximum speed inside lines should not be higher than 15m/s. RECOMMENDATIONS FOR REFRIGERANT LINES CONNECTIONS To locate the outdoor and the indoor units, refer to the following recommendations 2% INDOOR U. B OUTDOOR U. OUTDOOR U.

PIPE CONNECTIONS The units are factory pre-charged with Nitrogen (N 2 ). The installer should remove this gas and charge the units with refrigerant R-410A. Amount of refrigerant charge R-410A for the installation The amount of refrigerant R-410A for the system will depend on the size of connecting line between indoor and outdoor unit and on the expansion system of the indoor unit. Prior to charging the unit, a proper vacuum must be done. Finally, it is necessary to adjust the expansion system, with the unit already charged, to achieve the best features for the units, such as evaporating temperature, condensing temperature, discharge, etc. PRECAUTIONS TO BE TAKEN IN THE USE OF R-410A Refrigerant: R-410A Refrigerant is used in the unit; therefore, the following precautions characteristic of this gas should be taken: - The Vacuum Pump must have a Check Valve or Solenoid Valve. - Pressure Gauges and Hoses for the exclusive use with R-410A Refrigerant should be used. - The charge should be carried out in the Liquid Phase. - Always use scales to weight-in charge - Use the Leak Detector exclusive for R-410A Refrigerant. - Do not use mineral oil, only synthetic oil to ream, expand or make connections. - Keep pipes wrapped before using them and be very thorough about any possible dirt (dust, filings, burrs, etc.). - When there is a leak, gather what is left of the charge, create a vacuum in the unit and completely recharge with new R-410A Refrigerant. - Brazing should always be carried out in a nitrogen atmosphere. - Reamers should always be well sharpened.

PIPE CONNECTIONS CHARGE OF REFRIGERANT FOR THE SET: EXAMPLE: To install a KNHM 32E + indoor unit, with 22m refrigerant line length between outdoor and indoor unit, then the refrigerant charge must be calculated as follow: 1.-TABLE 1 (pg.18), for 22m of line length between indoor unit and outdoor unit, the line sizes are: liquid 5/8 and gas 1 1/8. 2.-TABLE 2 (pg.19), for line sizes of 5/8-1 1/8, the charge per meter line is: 177 gr/m x 22m = 3894 gr. 3.-TABLE 3 (pg.19), charge of refrigerant for the set with 0m of line length is: 6330 gr. 4.-To determine the carge of the set: Add charge of the refrigerant lines + charge of refrigerant indoor unit and outdoor unit. Total charge for the set: 3894 + 6330 = 10224 gr Note: If the outdoor unit includes factory pre-charged kit, only take care of weight of refrigerant per meter of line in TABLE 2. 112D to 152D units with 3 compressors are working using three capacity steps and with 4 capacity steps. See the picture below for the installation in the case of units with tandem compressor circuit. An additional gas line has to be used to assure the correct operation of the system.

OPTIONS 3.- COMFORT, PRECISION AND ENERGY EFFICIENCY LOW AMBIENT KIT 0º (COOLING UNITS ONLY, THE SERIES OF HEATING PUMP) It is a crank case heater for the compressor which allows unit operation in cooling mode until 0ºC of outdoor temperature. The purpose of the crank case heater is while the compressor is stopped, so that it can be properly lubricated when starts again. LOW AMBIENT KIT -15ºC (Only available for KSCM units). It regulates the fan speed with a pressure transducer, in order to control condensing temperature. This also includes a crankcase heater. Thus the unit will be able to operate in the cooling cycles when the outdoor temperature is below 19ºC (until -15ºC). A solenoid valve has to be fitted by the installer in the liquid line (indoor unit) to prevent liquid return to the compressor. See electrical diagram supplied with the unit for the connection. KIT LOW NOISE Each compressor is fitted with a compressor acoustic jacket this provides attenuation of the compressor noise that radiates from the unit. HOT GAS BY-PASS VALVE (Cooling only units). Hot gas by-pass valve is an that serves as extra stage of capacity control of the evaporator by injecting hot gas from high pressure side to the low pressure side after the expansion valve. It can reduce the capacity of the unit between 40 and 80%. HGBP valve has to be adjusted in the installation to regulate the capacity of the unit and taking into account evaporating in the compressor can not be below 2ºC to prevent ice formming in the indoor coil. The protection of indoor coil sensor is disabled by HGBP valve action. RUBBER ANTI-VIBRATION MOUNTS To install under the unit to avoid transmission of vibrations to the floor where unit is installed, while unit is operating. They are designed for low sensibility zones to vibration. SPRING ANTI-VIBRATION MOUNTS (Only 112-152D units) To install under the unit to avoid transmission of vibrations to the floor where unit is installed, while unit is operating. They are designed for medium and high sensibility zones to vibration. 4.- SERVICE FACTORY PRECHARGED This includes service valves and R-410A refrigerant charged in outdoor unit (for 0 meters of connection lines).

DRIVE INDOOR FAN MOTOR OPTION It includes the contactor and thermal switch, for indoor fan motor. 5.- COMUNICATION CAPABILITIES MODBUS It is possible to connect several units with a communication system (MOD BUS Protocol). 6.- EXTENDED LIFECYCLE PRECOATED COIL Special protection of the aluminum condenser coil fins, to protect it from aggressive external environmental conditions. 23

mode set on of f COMMISSIONING AND OPERATION PRELIMINARY CHECKS BEFORE FIRST OPERATION - Check that the power supply is the same as stated on the Rating Plate which is in agreement with the electrical diagram for the unit and that cable sizes are correct. - Check that tightness of the electrical connections to their terminals and to ground. - Check the control panel connections. (If the connection is wrong, the unit will not operate and the control panel display will not light). - Check with your hand that the fans turn freely. FIGURE FOR THE STANDARD UNIT CONFIGURATION FOR MODELS: 52D-64D-76D-86D CONTROL PANEL CHECK COMPRESSOR OIL LEVEL - Part of the compressor oil is pumped to the system when the compressor start, so for splits systems part of the oil can be placed in the system: piping lines, siphons, evaporator, etc. - Oil quantity in the system depends on refrigerant charge. The compressor can not work either refrigerant defect nor with an excessive amount of this one. - Depending on piping length, it can be necessary to add oil to the system. In case of having to add oil, remember the type of oil is synthetic POE. Original oil charge in the compressor is ICI Emkarate RL32-3MAF. This type of oil has to be used too in case of replacing the oil completely. On the other hand to add oil RL32-3MAF or Mobil EAC Artic 22C can be used. PRELIMINARY CHECKS AT FIRST OPERATION To start the unit, follow the instructions given in the User Manual for the control supplied with the unit (requesting operation in any of the modes, cooling, heating, or automatic). After a time lapse, the unit will start. With unit operating, check that the fans are turning freely and in the proper direction. COMPRESSOR SHOULD BE CHECKED THAT ROTATES IN THE CORRECT DIRECTION. - If you have return return lock three phases as check through it the correct rotation. - If you do not have return lock three phases, check the correct direction of rotation. The pressure on the suction side decreases and the pressure on the discharge side increases when the compressor is activated. - If the connection is wrong, the rotation will be reversed causing a a high noise level and a reduction in the amount of current consumed. If this occurs, the compressor s internal protection system will operate in shutting down the unit. The solution is to disconnect, switch the wires between two of the phases and connect the three again. ASTP Protection is included with the unit compressors. See "Failure diagnosis" for more information. WITH UNIT OPERATING, CHECK: - Low pressure and high pressure. - Evaporating and liquid temperature to calculate superheat and subcooling. - Adjust according this values refrigerant charge and/or expansion valve in case it can be neccessary. COMPRESSOR OIL LEVEL Oil level has always to be checked. When the compressor stops the level should be between 1/4 and 3/4 in the sight glass, while during operation the level should be between 3/4 and full. In case of having to add oil, remember the type of oil is synthetic POE. Original oil charge in the compressor is ICI Emkarate RL32-3MAF. This type of oil has to be used too in case of replacing the oil completely. On the other hand to add oil RL32-3MAF or Mobil EAC Artic 22C can be used. 24

MAINTENANCE PREVENTIVE MAINTENANCE PREVENTIVE MAINTENANCE PREVENTS COSTLY REPAIRS. BECAUSE OF THIS PERIODIC INSPECTIONS ARE REQUIRED: - GENERAL STATE OF THE CASING: Furniture, paint, deterioration due to bumps, rust spots, leveling and supporting, state of the shock absorbers, if installed, screwed panels, etc. - ELECTRICAL CONNECTIONS: State of hoses, tightness of screws, grounding, current draw of the compressor and fans and checking that the unit is receiving the correct voltage. - COOLING CIRCUIT: Check that pressure values are correct and that there are no leaks. Check that there is no damage to the pipe insulation, that the state of the coils is correct and that there are no chips or clogs retained by the air flow, etc. - COMPRESSOR: Inspect the oil level, if sight glass is present. Inspect the state of the silent block fixtures. - FANS: Check that fans turn freely and in the correct direction without excessive noises. - CONTROL: Check Set Points and normal operation. CORRECTIVE MAINTENANCE IMPORTANT MAKE SURE THAT THE UNIT IS COMPLETELY DISCONNECTED FROM THE POWER SUPPLY WHEN CARRYING OUT ANY TYPE OF WORK ON THE MACHINE. If some component in the cooling circuit must be replaced, follow these recommendations: - Always use original replacement parts. - Remove the entire refrigerant charge from the unit through the schrader valves located in the outdoor section. Create a slight vacuum as a safety measure. - Regulation prohibits the release on the refrigerant into the atmosphere. - If cuts must be made in the pipe work, use pipe cutters. Do not use saws or any other tools that produce filings. - All brazing must be carried out in a nitrogen atmosphere to prevent corrosion from forming. - Use silver alloy brazing rod. - Take special care that the flame from the torch is aimed in the opposite direction from the component to be welded and is covered with a wet rag in order to avoid overheating. Direction of the flame Wet rag Silver alloy welding rod Nitrogen Component to be welded - Take very special care if 4-way check valves are to be replaced since these have internal components that are very heat-sensitive such as plastic, teflon, etc. - If a compressor must be replaced, disconnect it electrically and un-braze the suction and discharge lines. Remove the securing screws and replace the old compressor with the new one. Check that the new compressor has the correct oil charge, screw it to the base and connect the lines and electrical connections. - Carry out the vacuum above and below through the schrader valves of the outdoor unit until -750 mm Hg is reached. Once this level of vacuum has been reached, keep the pump in operation for at least one hour. DO NOT USE THE COMPRESSOR AS A VACUUM PUMP. - Charge the unit with refrigerant according to the data on the Rating Plate for the unit and check that there are no leaks. PRECAUTIONS TO BE TAKEN IN THE USE OF R-410A Refrigerant: R-410A Refrigerant is used in the unit; therefore, the following precautions characteristic of this gas should be taken: - The Vacuum Pump must have a Check Valve or Solenoid Valve. - Pressure Gauges and Hoses for the exclusive use with R-410A Refrigerant should be used. - The charge should be carried out in the Liquid Phase. - Always use scales to weight-in charge - Use the Leak Detector exclusive for R-410A Refrigerant. - Do not use mineral oil, only synthetic oil to ream, expand or make connections. - Keep pipes wrapped before using them and be very thorough about any possible dirt (dust, filings, burrs, etc.). - When there is a leak, gather what is left of the charge, create a vacuum in the unit and completely recharge with new R-410A Refrigerant. - Brazing should always be carried out in a nitrogen atmosphere. - Reamers should always be well sharpened. 25
